In a Playground in Xcode 27 beta 6 I don't see a way to make a new page. It used to be File->New->Playground Page. That menu item is missing. The keyboard shortcut still exists, but it produces an error "No valid file actions for insertion." Am I missing an alternative? Or is this no longer possible?
Xcode 27 Playground New Page
Looks like playgrounds was integrated into canvas. The #Playground macro (in combination with import Playgrounds) is used to make a playground in the canvas.
It's a shift in the way I use playgrounds as throw-away experiments. Now those will be part of my app code if I forget to remove them which will be an annoyance.
